Jennifer Lopez is ready to settle down, again. The actress has been married three times, and she wouldn't rule out walking down the aisle once more.The 45-year-old "Booty" singer says in Elle U.K.'s October issue "I still believe in love. The nirvana man, he's out there somewhere. But you just have to work at it. You have to work at everything." When discussing her ex-husband Marc Anthony, Lopez said "When Marc and I first broke up, I did think, 'I wish I could have held this together.' But when you realize it's not the right thing for anybody, you think, 'OK, well how do we make this work, how do we make this better, how do we make this great for the children anyway?'"
